Abstract

All agree that progress in medicine depends on accurate knowledge of the fundamental laws which govern all life processes. The study of these laws is the province of General Physiology, whose rise and development have been most gratifying, particularly since it has made use of the rapid advances of chemistry and physics.

In such studies it seems best to avoid the complexities of higher organisms and to attack first of all the simpler problems presented by single cells. This plan has met with a good deal of success, so that General Physiology is largely concerned with the study of the
